PitchiPoy Rigify missing finger controls
It's easy enough to switch.

First you need to select the Pitchiboy metarig and go into Pose mode. Select the root of the finger (3rd from the tip) and go to the Bone properties view. Under the Rigify Type view it shows that the bone is set to create a "pitchiboy.simple_tentacle".



Click the Rig type field and select "finger". You need to do this to each finger you want to change.



Now when you generate the rig, you'll have the default finger controls. The Rigify system is pretty flexible, allowing you to mish and mash rig controls any way you need.
